Product Overview

GutterFoam, the easiest self installed gutter filter on the market. It is affordable and invisible from the ground. GutterFoam eliminates dangerous and dirty gutter cleaning so you can spend time doing the things you enjoy. Unlike other systems, installation is simple and easily installs in minutes. It does not require special tools. GutterFoam fits completely inside any 5 in. K style gutter-the most common style and size on the market today. When you reach a corner you make a miter cut using a scissors or a knife. GutterFoam seals out leaves while allowing large volumes of water to flow through quickly. No other gutter cover, screen or guard system works as effectively to keep debris from entering the gutter. Product comes in 4 ft. sections made from polyether outdoor durable foam, this lightweight insert won't crumble, dent, bend or cave in, allowing for satisfied customers. It also prevents mosquitoes from breeding in the gutter. The foam's main structure includes a UV stabilizer and a germicide. The coatings added provide added value by increasing the UV protection and protecting the foam overall from the elements.

High Maintenance
I installed these in my home about 8 years ago. I have oak and maple around my house primarily. These were inexpensive and easy to install. A few things- these shrink over time. So at each joint there will be a gap eventually. They also collect organics in the sponge from dead leaves, the whirly things off the maple and the fuzzy stems from oak. This has lead to me having to hose out, every year, the filters. I did it only a few times on my upper stories. I also used “Moss Out” to stop the moss from growing on top. In the last rain storm, I noticed massive amounts of water overflowing in many of my gutters. These guards were clogged. Today I hired a gutter company to install a new product and remove these. I still recommend these as a good alternative. They just require some (high) maintenance to keep them working. It might be as high as cleaning out your gutter every year!

Hello, thank you for your feedback and I apologize for any issues that you had with GutterStuff! We are always improving our UV & Germicide coating and there should be no need for any type of anti-moss treatment. It looks like you ordered the Original model which is covered under warrantee for 5 years and you had your filters for close to 8 years. We do offer different levels of protection that offer longer warrantee coverage and are better-suited for different types of environments that might have more humidity or exposure. If you have any questions about these other options, please feel free to give us a call @ (414) 446-8778. TjmWW

    DON'T RECOMMEND FOAM
    This is a long term review based on 2-3 years of use. The problem is despite that it installs easy and keeps most of the junk out of the gutter that it doesn't keep 100% of the junk out of the gutter. Foam is a porous material which creates two problems. First, if you have a newer roof like me the shingle material falls through the foam l and accumulates in the gutter. Issue #1. Issue #2. Junk accumulates on the top of the foam because it gets trapped which requires a lot more maintenance than you want to get it cleared out. Based on these factors it's too much of a headache. If you're going to spend time and money installing gutter guards then the only product I've found which works 100% are the micro-mesh guards.

    All gutter guards require some maintenance, but GutterStuff is the easiest to maintain. We recommend to occasionally brush or spray off the foam which will remove anything that does not blow off with the wind. A little maintenance will help GutterStuff performing year after year. TjmWW

      Gutterstuff was easy to install in less than an hour on a ranch home. We’ve been having heavy rains today and there are no overflows anywhere on the gutters. Before the rains came , leaves just blew right off. None getting stuck anywhere. This is a great product and money well spent. Beats the metal toppers hands down! Also they cannot be seen from the ground.

      I give this 3 stars because I just recently put them in and don’t know if they’ll stand the test of time.... Installation was a breeze (no tools necessary.) You can also cut the pieces with a pair of scissors or a razor (if you need less than a full piece.) I’d recommend wearing gloves- face mask cause there is some kind of flame retardant or insecticide you don’t want to breathe in- I read some bad reviews but I figure if they keep my drains from clogging they are worth it (I still expect they’ll need to be maintained)

      Overpriced, yet very effective if installed correctly, there is a top and a bottom, and must take care to keep grey side up. Product fits tightly, and can handle large volumes of water. If not installed the length of the whole gutter, it will trap debris and is not as effective. Important to stretch each section to open up pores and increase capacity to allow water to pass through. Overall, a good product.

      Easy to install. Insert and twist, creates seamless top that only allows water to enter and open cavity in gutter. Replaced 5" metal gutter system with vinyl. I have a lot of trees around my house and needed a way to keep gutters from clogging up. I installed them two weeks ago, so far, so good.

      It's too early to tell, but so far I'm happy with the product. I installed the filters two days ago but we haven't had any rain yet to get any sense of how the water flows through the foam. My gutters had hidden hangers inside so I had to notch out around each one. I used a coping saw to do the notching. The notching added some time to the installation process but it went smoothly. Most of my time was spent removing the old plastic gutter guard and cleaning out the gutters.

      K-Style Foam fits perfectly in the bulkhead. I have been looking for something that would keep the mice outside. So far so good. No cutting at all - fits great.

      SHOULD BE GUTTER GARDEN - PROMOTES WEEDS AND INSECTS
      Bought several hundred feet of gutter guard two years ago, worked good for the first year, than started to grow weeds in gutter, contacted Home Depot for 5 year warranty, they told me to contact the manufacturer, no store warranty is honored. I contacted manufacturer talked directly to the Gutter Guard President, he told me there is no warranty for weeds growing in his product, suggested I get a gutter company to clean out gutters yearly to prevent this.from occurring. However weeds cannot be removed from this material because they grow within the mess. This product also promotes insects in gutters, ants love this stuff. I have since paid to have all of it removed. Absolutely terrible product. I am really suprised the major stores still carry this item.
